Mndandanda wopita patsogolo mu mawonekedwe aulere
Magalasi opita patsogolo pamtunda wa mawonekedwe aulere ali ndi gawo lalikulu la 30% kuposa ma lens omwe amapita patsogolo.
Magalasi amkati opitilira patsogolo amaposa kapangidwe kakale kopitilira muyeso.
Kwa ovala osiyanasiyana, kuwerengera kwa mandala kukhathamiritsa kukhathamiritsa kumachitika molingana ndi kuwunika kwamankhwala, ndipo mawonekedwe enieni a lens yopita patsogolo amafananizidwa pasadakhale, ndiyeno pulogalamu yosungiramo kukumbukira y imagwiritsidwa ntchito pokonza zodula kwambiri kuti muchepetse zowonera. vuto lakusokoneza m'munda.Low, perekani mawonekedwe abwino kwambiri.Chidutswa chilichonse cha lens yopita patsogolo chomwe chapangidwa mwangwiro chimakhala ndi malo owoneka bwino komanso achilengedwe akutali, pakati ndi pafupi, ndipo ndizosavuta kusintha, kubweretsa mawonekedwe osayerekezeka kwa wovala!
● Kuwona mokulirapo: wovala amatha kuwona bwino mosalekeza kuyambira patali kupita kufupi ndi ma lens opita patsogolo, ndipo amatha kuwona mtunda wakutali, wapakati ndi waufupi bwino.
● Kuwona kwamphamvu kumamveka bwino : kuwala kukakhala kusuntha kuchokera kudera lina kupita ku lina, kusintha kwa maso kumakhala kwachilengedwe, ndipo sikumayambitsa chizungulire komanso kusawona bwino chifukwa chodumpha zithunzi.
● Chitonthozo chachikulu: masomphenya achilengedwe, mogwirizana ndi physiological optics, kusintha mofulumira ndikufupikitsa nthawi yosinthika.
● Maonekedwe ake ndi apamwamba kwambiri: mawonekedwe ake ndi okongola kwambiri kuposa ma bifocals, palibe mzere wogawanitsa wa mafilimu ang'onoang'ono, ndipo palibe annular blind zone.
Yang'anani pafupi ndikuwona patali, galasi limodzi logwiritsa ntchito zingapo, ntchito yokonza masomphenya, yomasuka kuvala
Kusuntha mapangidwe opita patsogolo kumalo amkati kumakulitsa kwambiri malo owonera gawo lililonse la mandala.Chinthu chinanso chomwe chimakhudza gawo la mawonedwe chimachokera ku aspheric kapena astigmatic aspheric design ya kumbuyo.Mapangidwe a aspheric amapanga utali wa curvature wa pamwamba pa lens lathyathyathya kotero kuti mandala akhoza kuyandikira pafupi ndi diso, chomwe chilinso chinthu chofunikira pakukulitsa mawonekedwe.
Kufotokozera kwa lens
Gwirani mfundo zofewa za asymmetric kuti zigwirizane ndi kutalika, pakati ndi pafupi
Ndipo dera la astigmatism kumbali zonse ziwiri lakonzedwa bwino kuti liwonjezere mawonedwe a lens ndi 35%
Zimapangitsanso wovalayo kukhala womasuka pakusintha kwa dera lililonse la kuwala komanso kosavuta kusintha.
